Definitions

  • the present invention relates to a washing machine equipped with a radiation drying unit; and, more particularly, to a washing machine capable of performing a drying operation by using far infrared radiation.
  • washing machines can be classified into two types: pulsator type and drum type.
  • a washer tub for accommodating laundry therein and a water tub for accommodating the washer tub therein are vertically installed in the washing machine, and the washing of the laundry is done by using a friction of water currents generated as a result of rotating a pulsator disposed in a bottom portion of the washing machine.
  • a rotary drum for accommodating laundry therein and a water tub for accommodating the rotary drum therein are horizontally supported in the washing machine, and the washing of the laundry is performed through drop movements of the laundry.
  • the drum type washing machine is gaining popularity because it has many advantages compared to the pulsator type washing machine. For example, by configuring the washing machine as drum type, its capacitance can be maximized and the phenomenon of the laundry being entangled with each other after being washed can be reduced. With such an increasing demand for the drum type washing machine, relevant technologies for improving the usability of the drum type washing machine have been rapidly developed.
  • FIGs. 1 and 2 There are respectively shown in Figs. 1 and 2 a perspective view and a cross sectional view of a conventional drum type washing machine.
  • the conventional drum type washing machine includes a washing machine main body 10 having a laundry loading/unloading opening 1 at a front surface thereof, a water tub 2 installed in the washing machine main body 10, a driving motor 3 installed below the water tub 2, and a rotary drum 5 horizontally installed inside the water tub 2 such that it is rotated by the driving force of the driving motor 3. Further, a door 6 for opening or closing the laundry loading/unloading opening 1 is installed at the front surface of the washing machine main body 10. Also, installed in an upper portion of the washing machine main body 10 is a drying unit 20 for drying laundry by removing moisture contained in the interior air of the washing machine while circulating it. Moreover, the drum type washing machine further includes a belt mechanism 25(see Fig. 2 ) for connecting the driving motor 3 and the rotary drum 5.
  • the drying unit 20 has a fan 30 installed inside the washing machine main body 10, a heater 32 installed at one side of the fan 30, and an air flow duct 34 forming an air flow passage extended from the fan 30 to a front portion of the rotary drum 5 via the heater 32.
  • the drum type washing machine with the drying function configured as described above performs a washing operation by agitating the laundry vertically by way of rotating the rotary drum 5. After the completion of the washing operation, a water-extracting operation is performed by spinning the rotary drum 5 at a high rotational speed.
  • a drying operation for drying the laundry is performed by means of the drying unit 20.
  • the drying operation involves directing the air outside the water tub 2 to the heater 32 by rotating fan 30, heating the air by the heater 32 while the air flows through the heater 32 and then blowing the heated air into the rotary drum 5 which is slowly rotated.
  • the laundry may be damaged in case the temperature of the air is not controlled precisely. Further, even though the laundry is dried, there is likelihood that the laundry is infected or has an unpleasant odor because it contacts the high-temperature damp air during the drying process
  • a washing machine using far infrared radiation for the drying operation (see, for example, Korean Patent No. 10-0329267 ), wherein a drying unit employed therein includes a heater 42 installed at a central portion of a rotary drum 40 and a heater protection member 44 for surrounding the heater 42, as illustrated in Fig. 3 .
  • the heater 42 is a far infrared radiation heater.
  • the drying operation is performed through a flow of hot air. Specifically, high-temperature dry air that has passed through the heater 42 is dispersed radially from the central portion of the rotary drum 40, thereby drying the laundry therein.
  • US 5,459,945 discloses a vacuum assisted system for drying articles of clothing with recaptured heat including an evaporation chamber and a condensation chamber.
  • the evaporation chamber is enclosed inside the condensation chamber. Heat transfers from the condensation chamber to the evaporation chamber when a vapour condenses on the exterior of the evaporation chamber. Pressure is reduced in each chamber by an automated regulation system which pumps vapour from between the chambers to optimise drying.
  • the far infrared radiation heater is disposed at the central portion of the rotary drum in the conventional configuration, loading and unloading of the laundry into and from the rotary drum becomes rather troublesome and it is highly likely that the laundry would be damaged by contacting the heater protection member directly. Moreover, since no system for controlling the temperature of the hot air from the far infrared radiation heater is provided, the laundry may be damaged due to the excessively high-temperature air blown thereto.
  • an object of the present invention to provide a washing machine having a drying unit capable for drying laundry at a middle or a low temperature by using far infrared radiation, thereby drying the laundry efficiently while concurrently sterilizing and deodorizing it without causing a damage of fiber.
  • a washing machine equipped with a radiation drying unit including: a rotary drum for accommodating laundry therein; a water tub for accommodating the rotary drum rotatably; a far infrared radiation generator for generating a radiant ray in a far infrared wavelength; a radiation transmission portion for transmitting the radiant ray generated by the far infrared radiation generator to the rotary drum; a radiation controller for controlling an amount of the radiant ray transmitted from the far infrared radiation generator to the rotary drum; and a convection fan for circulating air by rotating in forward and reverse direction depending on an internal temperature of the rotary drum, wherein the radiation transmission portion includes a black body for performing a complete absorption an a complete emission of the radiation.
  • the washing machine having the drying unit in accordance with the present invention can perform the radiation drying of the laundry at the middle or low temperature, which is identical to the radiation drying mechanism by the sunlight. Therefore, an energy loss that might be caused by the dry air whose temperature is raised excessively high can be prevented, and various damages of the laundry that might be incurred by the contact with the hot air can also be prevented. Further, by using the far infrared radiations, the laundry can be sterilized and deodorized while it is dried without suffering from damages of fibers. As a consequence, the washing machine with the drying unit of the present invention can be made environment friendly.
  • the technical characteristic of the present invention resides in that it employs a middle or low temperature radiation drying mechanism for drying laundry at a middle or low temperature by using far infrared radiation instead of high-temperature airflow. Specifically, by emitting far infrared rays by means of a heating element and transmitting the far infrared rays to the laundry while controlling their radiation amount, exposure of the laundry to excessively high-temperature air can be avoided, so that the laundry can be dried at the middle or low temperature without being overheated.
  • the laundry by drying the laundry through the middle or low temperature radiation drying mechanism, the same effect as attained when drying the laundry by natural sunlight can be obtained and, besides, the laundry can be sterilized and deodorized by the far infrared radiations without suffering from damages of fibers.
  • Fig. 4 shows a configuration of a washing machine in accordance with a preferred embodiment of the present invention.
  • a radiation drying unit in accordance with the present invention is shown in Fig. 4 to be applied to a drum type washing machine, it can be applied to drying systems of various types of washing machines including a pulsator type washing machine.
  • a horizontally oriented rotary drum 110 is rotatably installed in a cabinet 100 of the washing machine, and a water tub 120 is also disposed in the cabinet 100 to surround the rotary drum 110.
  • a convection fan 130 is further installed in the cabinet 100.
  • the convection fan 130 suctions external air by rotating in forward direction while exhausting air from the rotary drum 110 and the water tub 120 by rotating in reverse direction.
  • a reflection element 112 is coated on the inner cylindrical surface of the rotary drum 110 to reflect far infrared rays from a far infrared radiation generator 160 to be described later.
  • the drying unit in accordance with the present invention is installed between the outer bottom portion of the rotary drum 110 and the inner bottom portion of the water tub 120.
  • the drying unit communicates with the convection fan 130 via an air flow duct 140 for allowing the external air and circulation air to flow therethrough.
  • Reference numeral 150 is an air outlet for discharging air from the rotary drum 110 and the water tub 120.
  • the drying unit includes the far infrared radiation generator 160; a radiation transmission portion 170 for connecting the far infrared radiation generator 160 and the rotary drum 110 to thereby allow them to communicate with each other; and a radiation controller 180 installed at an end side of the radiation transmission portion 170 to control the radiation amount transmitted from the radiation transmission portion 170.
  • the far infrared radiation generator 160 is activated by a heating element 166 and emits a radiant ray in a far infrared wavelength range.
  • the far infrared radiation generator 160 includes a duct-type housing 162 communicating with the radiation transmission portion 170 and the heating element 166 incorporated in the housing 162 while maintaining an interval from the inner surface of the housing 162.
  • the inner surface of the housing 162 is coated with a far infrared radiation element 164, so that the far infrared ray radiation element 164 is activated by the heating element 166 and the far infrared rays can be radiated.
  • the housing 162 can be fabricated by an injection molding using a mixture of the far infrared radiation element 164 and a binding material mixed with a predetermined mixture ratio.
  • the housing 162 can be fabricated by a coating method using 3 wt% of far infrared radiation element 164 and predetermined coating adhesive.
  • Fig. 5B illustrates a modification of the far infrared radiation generator 160.
  • the modified far infrared radiation generator is formed of a casing 163 with a preset thickness and is configured to communicate with the radiation transmission portion 170. Further, a hot wire 167 that emits heat by an external power supply is embedded in the casing 163.
  • the heating element 166 installed in the housing 162 or the hot wire 167 embedded in the casing 163 are for emitting the far infrared rays and are operated below a conventional heater heating temperature.
  • the radiation transmission portion 170 transmits the radiant rays through a black body radiation mechanism by completely absorbing the radiant rays and then completely emitting the absorbed radiant rays.
  • the radiation transmission portion 170 is formed as a duct incorporating therein the black body for absorbing and re-emitting the transmitted radiant rays.
  • the duct-type radiation transmission portion 170 is formed to contain a black body material.
  • a black body material capable of carrying out a complete absorption and a complete emission of the radiant rays in the far infrared wavelength range can be coated on the inner surface of the duct-type radiation transmission portion 170.
  • the radiation transmission portion 170 which is configured as the black body whose inner surface is formed to contain a material with a high albedo (reflectance), can absorb and re-emit the radiant rays without suffering from dispersion or radiation loss.

  • the radiation controller 180 is configured as a shutter made of an opaque radiation absorbent element capable of diminishing or absorbing the radiant rays in the far infrared wavelength range. That is, the control of the radiation amount can be implemented by the camera shutter-like mechanism for controlling the duration of the radiation, while noting that a modification thereof is also possible.
  • the drying unit configured as described above, generation of heat during the drying process is performed at a temperature lower than that set to heat wash water, so the laundry can be dried by the middle or low temperature radiation drying mechanism by using far infrared rays generated by the far infrared radiation generator 160.
  • the heating element 166 incorporated in the far infrared radiation generator 160 is heated to activate the far infrared radiation element 164 installed inside the housing 162, so radiant rays in a far infrared wavelength range are emitted from the far infrared radiation element 164.
  • the radiant rays are then transmitted via the radiation transmission portion 170 to be eradiated to the laundry accommodated in the rotary drum 110.
  • the far infrared rays penetrate the laundry by virtue of its penetrating power and penetration depth, thus evaporating the moisture contained in the laundry.
  • the laundry can be dried at a middle or a low temperature without suffering from a rapid and intensive increase of the temperature, as if it were dried by natural sunlight.
  • the inner cylindrical surface of the rotary drum 110 is coated with the far infrared ray reflection element 112
  • the drying of the laundry can be dried by using the far infrared radiation more effectively.
  • the overheating of the laundry that might be caused by a continuous exposure to the radiant rays during the drying process can be prevented, so that the laundry can be dried by the far infrared radiations transmitted into the rotary drum 110 at an optimum radiation amount.
  • the convection fan 130 can be operated to circulate air through the washing machine, to thereby assist the drying process through the far infrared radiation.
  • the convection fan 130 suctions the external air of the washing machine and directs it into the rotary drum 110 when it rotates in forward direction.
  • the convection fan 130 can be configured to communicate with the far infrared radiation generator 160. This configuration allows some of the residual heat generated by the heating element 166 of the far infrared radiation generator 160 to be transmitted to the inside of the rotary drum 110, thereby improving the drying function.
  • the temperature of the air heated by the residual heat is below a temperature level at which the radiant rays in the far infrared wavelength range heats the laundry, so a supply of excessively high-temperature air to the laundry can be prevented.
  • a temperature sensor can be additionally installed, e.g., inside the water tub 120 in a vicinity of the end portion of the radiation transmission portion 170.
  • the above configuration allows a flow of only the middle or low temperature air within the water tub 120. This airflow does not interfere or diminish the radiant rays in the far infrared wavelength, so the middle or low temperature drying process by the radiation can be performed without being affected by the airflow.
